Experimental Studies on Impact Characteristics of Steel Fibre Reinforced Concretes

摘要

Research work carried out so far towards the development of concrete that exhibits improved impact resistance than conventional concrete. There are several situations in which concrete structural elements are subjected to impact loading. The behaviour of concrete under impact loads is far from adequate and there is significant variability in the published literature. The primary reason for this is the lack of a standardized technique of testing concrete under impact. In this project, an attempt is made to study the impact resistance of fibrous concrete using ACI drop weight Impact tester. Two grades of concrete's namely Ml and M2 are consideredin this investigation with 0.5, 1.0, 1.5 and 2.0% dosage of steel fiber. The experimental test results of steel reinforced fiber concrete are compared with plain concrete and conclusions are arrived.
